After Cube Action Team rider Greg Callaghan stormed to victory at the Irish round of the 2016 Enduro World Series on a Stereo 140 29er, the German brand decided it needed to add a more enduro-focused big-wheeler to its line-up. The result is the Stereo 150 29, and it’s already helped Greg gain a third-place overall finish last year. But is it just as potent an enduro weapon for us lesser mortals?
Cube Stereo 150 C:68 TM 29 frame
Cube’s new enduro weapon gets big wheels and an aggressive suspension feel Cube
The C:68 frame of the flagship TM model is built from high-grade carbon fibre, which has had its carbon-to-resin ratio boosted with some carbon thread weaving to give thinner (and therefore lighter) walls. There are also nano particles in the resin, which are said to reduce the risk of delamination. Cube offers two cheaper C:62 carbon models, but no alloy option.
There’s 150mm of travel out back, courtesy of Cube’s familiar ETC 4-Link four-bar linkage. It’s adjusted the kinematics for the Stereo 150 29, to give a much more progressive stroke, which improves confidence and control when the bike is pushed to the limits of its travel.
The frame itself doesn’t have the stretched and lowered geometry you might expect of the latest generation of enduro bikes, though. Its reach — 457mm on the 20in size — is quite short by modern standards, and the 66-degree head angle isn’t super-slack.
The 34mm of bottom-bracket drop keeps your weight low, though, and the 75.5-degree seat angle puts you nicely over the pedals when seated.

Cable routing is fully internal and there’s even a port for a Shimano Di2 battery Cube
This top-end build comes with a 2019 Fox 36 fork with the new FIT GRIP2 damper, plus a Float X2 piggyback shock. The price is kept in check by use of SRAM’s mid-range GX Eagle groupset and Code R brakes. Newmen wheels aren’t well known in the UK, but the 30mm internal width of the Evolution SLs specced here gives a good platform for the excellent Schwalbe Magic Mary and (updated) Hans Dampf tyre combo.
Cube Stereo 150 C:68 TM 29 ride experience
The extra progression through the stroke is the most noticeable change over Cubes of old. Late in the travel, there’s a very obvious ramp-up — it’s not quite ‘blows your feet off the pedals’ firm, but the bike certainly doesn’t feel sofa-like as it gets deep into its stroke.
This may sound like a negative, but this is a machine built for the EWS race track, where an aggressive suspension tune is necessary to stop it repeatedly bottoming out over the big hits. The soft initial stroke gives plenty of grip, boosted by the low pressures you can run in the Schwalbe rubber, and that extra mid-stroke support and firmness at the deep-end improve control.
The Cube is well-suited to tight and twisty tracks Cube
Typically for Cube, the geometry isn’t radical. Compared to its EWS rivals, the Stereo 150 29 looks short. This means it doesn’t offer sled-like confidence on the steepest or loosest trails, although the low bottom-bracket and ground-hugging suspension do keep things in control.
It’s a bike that you’ll get on with better if you’re smart about line choice, rather than just slamming over the top of everything. The Cube is well-suited to tight and twisty tracks, though, where its quick-turning nature will win you over.
